I have had a problem in the shop where I have many different stashes of wood. This has made the shop cluttered and hard to find anything useful when I needed it. I have made a wood rack from 2x4s. It is a series of wood frames held together with mortise and tenon joints. The frames are held together at the top and bottom to form cubbies for different sized pieces of wood. This should help keep the scrap wood in the shop organized.
